All natural materials (rubber, protein, cellulose) and plastics contain molecules as their smallest particles, which in turn consist of a large number of atoms. The term ‘macromolecule’ tak...")

The term "fracture" refers to the macroscopic separation of the material leading to the loss of the load-bearing capacity of the body.
